ActivityDesignerOptionsAttribute	Specifies drill-down and node viewing mode for an ActivityDesigner, such as Flowcharts, that are used to compose activities.
ArgumentAccessor	A class containing a get/set delegate pair to access an argument in an activity instance.
CachedResourceDictionaryExtension	Provides a cached dictionary that associates resource dictionaries with their URIs.
ClipboardData	Represents the data passed around with the clipboard.
ContextItem	Represents a base class from which all context items must derive. This class is abstract.

DynamicArgumentDesignerOptions	Provides options for the dynamic argument designer.
DynamicArgumentDialog	Represents a dialog box for a dynamic argument element.
EditingContext	Contains contextual state information for a designer, such as the WorkflowDesigner. This includes permanent state information, such as the list of services running in the designer. It also includes transient state consisting of context items including the set of currently selected objects as well as the editing tool being used to manipulate objects on the design surface.
ObjectReferenceService	This interface is used by Visual Studio integration to acquire an AppDomain serialization friendly reference to an object.
ServiceManager	Implements IServiceProvider and provides access to services offered by the editing context.
SourceLocationUpdatedEventArgs	Provides data for the SourceLocationUpdated event.
TypeResolvingOptionsAttribute	Used to configure how a Windows Workflow Designer initializes type-resolver and type-browser dialogs to enable a user to select a type for arguments, variables, and generic type activities.
UndoEngine	Provides undo and redo operation implementations for designers.
UndoUnit	Represents a single unit of undoable work. Such a unit is added to an undo stack, and methods are provided to traverse the stack and perform an undo action on each unit.
UndoUnitEventArgs	Represents the argument that is passed to the UndoUnitAdded event.
WorkflowDesigner	Provides a designer canvas, which renders the visual representation of a workflow model as it is being designed.
WorkflowDesignerColors	Enables colors and color gradients to be associated with aspects of the elements and shell bars used in the Windows Workflow Designer user interface.
WorkflowDesignerIcons	Represents the workflow designer icons.
WorkflowDesignerIcons.Activities	Represents the designer icons for the activities in workflow.

WorkflowDesignerIcons.DesignerItems	Provides the items available when working with the workflow designer.
WorkflowElementDialog	Represents a dialog box for the workflow element.
WorkflowFileItem	Represents a ContextItem that is published in the editing context and that provides information about the file that the current editing session is based on. Note that it is possible that the WorkflowFileItem value is null, for instance if a WorkflowDesigner operates directly on an object instance and does not serialize into a file-based format.
WorkflowItemPresenter	Provides a visual editor to edit ModelItem objects, and provides an area for the user to drag and drop, and otherwise edit composed elements.
WorkflowItemsPresenter	Represents a control that can be used to present a collection of objects on a design surface.
WorkflowViewElement	Specifies the base class for any UI element that appears on the Windows Workflow Foundation designer canvas and that visually represents an instance of an atomic item that can be edited.
XamlLoadErrorInfo	Contains information about the error generated by the XAML Reader when loading an XML file, including the name of the file and the location in the file where the error occurred.

Interfaces

IActivityTemplateFactory	Defines the factory method that a class implements to create a template that encapsulates "placeholder" Activity objects.
IActivityTemplateFactory<T>	Represents the generic IActivityTemplateFactory.
IActivityToolboxService	Represents a service used to update Toolbox contents from a Designer.
ICompositeView	Provides methods to copy, cut, move, delete, and paste objects.
ICompositeViewEvents	Handles events that can occur during the display of ICompositeView items.
IIntegratedHelpService	Defines the contract between Visual Studio 2010 and the Windows Workflow Designer for integrated help provided.
IModalService	Enables notification to a host application that a modal dialog is displayed.
IMultipleDragEnabledCompositeView	An extension interface for ICompositeView to better support multiple drag/drop.
IWorkflowDesignerStorageService	Provides a service available to the Windows Workflow Designer host to store and retrieve data.
IXamlLoadErrorService	Defines how the Visual Studio host displays the list of errors generated by the XAML reader when loading the XAML file.

PublishServiceCallback	A delegate that references a method that publishes an instance of a service.
PublishServiceCallback<TServiceType>	A generic delegate that references a method that publishes an instance of a service.
SubscribeContextCallback	Defines a callback method that will be invoked when a context item changes.
SubscribeContextCallback<TContextItemType>	Defines a callback method that will be invoked when a context item changes.
SubscribeServiceCallback	Represents a delegate that is a callback for service subscriptions.
SubscribeServiceCallback<TServiceType>	Represents a generic delegate that is a callback for service subscriptions.
